Job number
A job number must be allocated to each connection that should be used by handler modules.
This number is used to access the connection from the PLC program. The job number
together with the frame offset number determines the connection. This precludes multiple
assignments. The job number and the respective frame offset number must be supplied in the
control program.
Range: 1 to 199
Priority
This parameter specifies the priority of the message for the CP143plus. The priority may
range from 0 (highest priority) to 41 (lowest priority).
When establishing a connection, priority 0 and 1 connections are so-called static
connections. This means that the connection will be re-established, if possible, should it
have been terminated (e.g. by the reset handler module).
Range:0to41
Job type
Here you specify the type of job. The following job types are available:
• Send transmission of unstructured data.
• Receive reception of unstructured data.
Type
Here you must specify the type of transfer. You may select to send unsecured messages to a
specific receiver, to a selected group of receivers or to all receivers.
• Point-to-point job Point-to-point job an unsecured job for a single station.
• Multicast an unsecured job for selected multicast-circuits.
When you select multicast, the multicast-identifier is
transferred to the ethernet-address. You determine the multicast
circuits by means of the last three nibbles of the ethernet address.
• Broadcast transmits a single message to all the participants that have been
allocated the pre-set broadcast address or reception of single
messages from participants that transmit via the pre-set broadcast
address.
The H1 broadcast address is FFFFFFFFFFFFh.
